usb: gadget: aspeed: Fix EP0 stall handling When stalling EP0, we need to wait for an ACK interrupt, otherwise we may get out of sync on the next setup packet data phase. Also we need to ignore the direction when processing that interrupt as the HW reports a potential mismatch. Implement this by adding a stall state to EP0. This fixes some reported issues with mass storage and some hosts. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
